Get map z / elevation at specific coordinates?

[Pithikos]

Is there a function to get the z elevation at specific coordinates x and y? A searched a bit and didn't find anything, neither in Synced, Unsynced or Constants.

Spring.GetGroundHeight

( number x, number z ) -> number y

Spring.GetGroundHeight

( number x, number z ) -> number y

Thanks! I was searching in the map sections
